Technical Specifications & Dimensional Parameters

Key Features & Performance Advantages

Zero-Clearance High-Rigidity Design for Pitch Control Accuracy

The 3.2MW wind power slewing ring adopts a double-row four-point contact ball structure with professional zero-clearance design, eliminating rotational backlash during blade pitch adjustment, ensuring micron-level accurate control of blade angle, and maximizing wind energy capture efficiency and power generation stability of the wind turbine.

Extreme Environmental Adaptability & Long-Term Reliability

Equipped with a four-lip composite sealing structure, it effectively blocks dust, moisture, salt spray and other corrosive media, fully adapting to harsh outdoor, coastal and offshore wind farm environments. The plastic-coated cage provides excellent corrosion resistance, while reducing operational noise and vibration, ensuring long-term stable operation of the pitch system.

Ultra-Strong Load-Bearing Capacity for Variable Wind Loads

The optimized double raceway design can simultaneously bear complex combined loads such as huge axial load, radial load and overturning moment generated by extreme wind speed impact, ensuring the safety and stability of the wind turbine under typhoon, strong wind and other extreme weather conditions.

Applications & Compatible Equipment

This wind power generation slewing ring is specially designed for the pitch control system of 3.2MW onshore and offshore wind turbines, and can also be adapted to 3MW-3.5MW wind turbine models with matching installation dimensions and load requirements, serving the full life cycle of wind power projects from initial construction to later operation and maintenance.

Installation, Operation & Maintenance Guidelines

Before installation, inspect the flatness of the turbine hub mounting surface, remove all burrs and contaminants, and ensure the mounting base meets the design rigidity requirements;

Use a torque wrench to tighten mounting bolts in a symmetrical cross sequence, strictly following the specified torque value to avoid uneven stress;

Fill with special wind power grease before commissioning, and perform regular grease replenishment and seal inspection according to the wind farm maintenance manual;

Avoid frequent overload impact beyond the design load range, and regularly monitor the operating temperature and vibration of the slewing ring.
